I'm fine with this change, but just a strange data point, since the purpose in 7-bit was to be able to use _mm_madd_pi16 or similar: I noticed that for commit 9aa8e3a2 that I actually had a slight loss of performance on Loongson (1.8%) but a gain of 8.3% on ARM/iwMMXt. _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
